Physical Design
The Raspberry Pi 5 retains the credit-card-sized form factor (85mm x 56mm) of previous flagship models, ensuring compatibility with many existing setups. However, it requires a new case due to layout changes and increased thermal demands. The official Raspberry Pi 5 case ($10) includes an integrated fan for active cooling, and the Active Cooler ($5) is recommended for heavy workloads to prevent thermal throttling. The board also features cleaner edges due to improved manufacturing processes like intrusive reflow for connectors and routed panel singulation.
Operating System and Software
The recommended operating system is Raspberry Pi OS (based on Debian Bookworm), optimized for the Raspberry Pi 5’s hardware. It is available in:
- Full: Includes a desktop environment and pre-installed software for general use.
